What happens in the event of non-payment of the supplementary solidarity health insurance (C2S)?

Verified 05 March 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)

If you have limited resources, complementary health solidarity (C2S) helps you with your health expenses. It supplements the Social Security reimbursements. She is free or paid depending on your income level. If it pays, you must pay your share of C2S (€1 per day and per person maximum). If you do not pay all or part of this payment corresponding to 2 monthly installments in a row, your right will be suspended within 30 days.

At the end of that 30-day period, the suspension shall be pronounced in the case of:

  • Non-payment of the full amount due
  • Or lack of agreement between you and the managing body on payment rules.

However, you have a new 30-day deadline to pay.

Beyond these 30 days, you no longer benefit from the refund of the additional part. This means that your healthcare expenses are reimbursed only through Social Security.

Please note

If you make a request for renewal of the right to C2S or new admissions, you must have paid the amounts requested. If not, you cannot be assigned C2S for 2 years. However, these rules do not apply if you have benefited from:

  • Help with the payment of your participations
  • A reduction or even partial reduction of your debt
  • A payment schedule.
